## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a pitching movement training device teaching athletes proper hand positioning upon either a baseball or a softball while throwing specific pitches.
2. Description of the Related Art
Whether considering baseball or softball, most experts will agree that pitching is truly an art form. The pitcher is required to coordinate finger motion and positioning upon a ball with arm and body motion in a manner controlling the movement of the ball as it moves from the pitchers hand to the plate where a batter attempts to strike the ball with a bat. All of this must be coordinated without allowing the batter to predetermine which pitch the pitcher intends to throw.
Many beginning players unfortunately do not appreciate the importance the proper positioning of their fingers, that is, gripping, plays in correctly executing various pitches. In many instances young players simply pick up a ball and begin throwing, dangerously contorting their arm to achieve different spins upon the ball. Without the aid of trained professional, it is virtually impossible for a younger player to properly determine finger position upon a ball in order to properly execute different pitches. Even when a young player has access to a trained professional for advice, the professional is not always present to reinforce the proper finger positioning and bad habits develop when young players begin improperly positioning their fingers upon a ball during throwing activities.
With the foregoing in mind, the present inventor has developed a pitching movement training device providing tactile and feedback to young pitchers in a manner that allows for ready adjustment to teach and practice various pitching grips.

The position of the holes is chosen so as to permit a variety of peg 14, 114 arrangements allowing users to adjust the peg arrangement so as to training for different pitches as discussed below in greater detail.
The present training device 10, 110 is used in teaching athletes proper hand positioning upon a ball while throwing specific pitches. The method involves providing a plurality of pegs 14, 114 and a ball 12, 112, the plurality of pegs 14, 114 being shaped and dimensioned for selective attachment to the ball 12, 112. The pegs 14, 114 are selectively secured to the ball 12, 112 at predetermined locations about the outer surface 18, 118 of the ball 12, 112, the user's fingers are positioned relative to the pegs 14, 114, and the user is instructed to throw a pitch with a specific hand motion.
In accordance with a baseball embodiment as shown with reference to FIGS. 1 to 5, the baseball 12 is provided with ten (10) holes 21-30 (in order to facilitate use of the present ball the holes are marked 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 on the outer surface 18 of the ball 12). In accordance with a softball embodiment as shown with reference to FIGS. 7 to 10, the softball 112 is provided with seven (7) holes 121-127 (in order to facilitate use of the present ball the holes are marked 1, 2, 3, 4, 5, 6 and 7 on the outer surface 118 of the ball 112). Referring first to the baseball embodiment, the holes 21-30 are arranged about the baseball 12 to permit training of various pitches and are accordingly arrangement based upon their relative proximity to the seams formed about the baseball 12.
As a reference for the following discussion, a conventional baseball 12 can be thought of as including a single seam 32 formed in a serpentine pattern for the purpose of securing first and second cover members 34, 36 about the core (not shown) of the baseball 12 so as to define the outer surface 18 of the baseball 12. Although serpentine, the single seam 32 of a baseball 12 is highly symmetrical and includes first and second narrow seam sections 40, 42 connecting first, second, third and fourth horseshoe shaped seam sections 44, 46, 48, 50. The first and second narrow seam sections 40, 42 are positioned on opposite sides of the ball 12 and are each composed of adjacent first and second lateral seam members 52, 54, 56, 58 at their closest points. The sole difference between the first and second narrow seam sections 40, 42 resides in the fact that the axis extending between the adjacent first and second lateral seam members 52, 54, 56, 58 of the respective first and second narrow seam sections 40, 42 are oriented at 90 degrees relative to each other.
With regard to the first, second, third and fourth horseshoe shaped seam sections 44, 46, 48, 50, these are looped sections extending on opposite sides of the respective first and second narrow seam sections 40, 42.

The third, sixth, fourth, and seventh holes 123, 126, 124, 127 are formed adjacent the first narrow seam section 140 along a line transverse to the longitudinal axis extending between the first and second lateral seam members 152, 154 making up the first narrow seam section 140. The third, sixth, fourth, and seventh holes 123, 126, 124, 127 are positioned closer to the first horseshoe shaped seam section 144 than the second horseshoe shaped seam section 146. In particular, the third hole 123 is formed in the second cover member 136 adjacent the first lateral seam member 152 of the first narrow seam section 140 (corresponding to the arcuate connecting seam member 190 of the fourth horseshoe shaped seam section 150), the sixth hole 126 is formed in the first cover member 134 adjacent the first lateral seam member 452 of the first narrow seam section 140 (corresponding to the arcuate connecting seam member 190 of the fourth horseshoe shaped seam section 150), the fourth hole 124 is formed in the first cover member 134 adjacent the second lateral scam member 154 of the first narrow seam section 140 (corresponding to the arcuate connecting seam member 188 of the third horseshoe shaped seam section 148), the seventh hole 127 is formed in the second cover member 136 adjacent the second lateral seam member 154 of the first narrow seam section 140 (corresponding to the arcuate connecting seam member 190 of the fourth horseshoe shaped seam section 150).
The fifth hole 125 is formed along the second narrow seam section 142 toward the fourth horseshoe shaped seam section 150. In particular, the fifth hole 125 is formed in the second cover member 136 adjacent the second lateral seam member 158 (corresponding to the arcuate connecting seam member 184 of the first horseshoe shaped seam section 144) of the second narrow seam section 142.
Each of the various holes described above is shaped and dimensioned for selective attachment of a peg therein. In accordance with a preferred embodiment, each hole includes internal threading for engagement with external threading along the outer distal end of the various pegs used in accordance with the present invention.
